Double bed and matress in a Fiat Tipo.
Two people, five bikes and all of my friend’s worldy goods in a Mondeo hatch. I also managed to move house in that car, after two bikes had moved in a previous trip (I didn’t own any furniture at the time)
We had 70 bricks in the OP’s car, volume was fine, more of a weight issue. Landy 110 barely noticed 100 roof tiles
You can get a ride-on mower in the boot of a Montego estate, just need to pop the steering wheel off (the mower!) for height reasons.
Firewood and three people in a two seater berlingo. Drove out with me in the comfy passenger seat, housemate in the boot. Filled it with blown down branches for the bonfire, my turn in the back on the way home, not comfortable!
